Beside this, the moon causes that ebbing and flowing of the ocean called the tides. These keep it from being stagnant and prevent its becoming putrid. Were it not for the moon, the whole ocean would be unfit for the fishes that live in it, and they would all die. Men and beasts, too, would also perish from the unhealthiness of the land, were not the sea kept pure by the tides.

Charles sitting with his book in his hand; his mother at work.

Charles. Mother! is it almost school-time?

Mother. No; you have full half an hour.

Charles. Only half an hour? Will you hear me try to say this lesson again?

Mother. No, for I am sure you will say it no better than before.

Charles. Why, mother?

Mother. Because you have not been studying. I have been looking at you from time to time, and have scarcely seen your eyes fixed once on your book.
